dAHLer’s Exhaust Flap/Valve Controller is the perfect addition to your BMW to take control of the exhaust sound.

With the device installed you can manually open and close the standard built-in exhaust flap of your BMW at any time. It operates at the push of a button on the in delivery included remote control or can be programmed to your mirror buttons, so the system will be very well integrated.

Installation of the dAHLer Exhaust Flap Control Module in your BMW is easy and can be carried out by anyone with a little manual skill. The device is a direct plug in to the existing (OEM) harness. You pull out the original plug and connect it to the socket. The other plug is then connected to the socket on the exhaust flap and the connection is done.

The complete installation takes place in the trunk and under-body. You look for a cable duct or unused sealing plug that leads from the inside to the outside. Power supply comes directly from the original plugs and there is no need to lay cables through the interior of the vehicle.

With dAHLer’s smart Exhaust Flap/Valve Controller, one cannot close the exhaust flap permanently. This is for safety reasons as when driving at full throttle with the exhaust flap closed it could damage the engine in a long term.
